  1. When Do Autoregressive Sequence Models Forecast Physical Wavefields? A Controlled Study on Synthetic Seismograms

    Researchers have investigated the stability of autoregressive sequence models when forecasting long-horizon physical wavefields, such as seismograms. Their study, using a model called SeismoGPT on synthetic seismograms, found that multi-token prediction significantly stabilizes the forecasting process. Additional gains were observed with a horizon-embedding hybrid prediction head and a cross-horizon STFT-magnitude coherence loss, though performance critically depends on a specific context-ratio threshold.

  2. Data-Driven Forecasting of three-Component Seismograms Using Transformer Architectures

    Researchers have developed SeismoGPT, a transformer-based model designed to forecast seismic waveforms. This model operates autoregressively in the time domain, continuing waveform data beyond observed seismic arrivals. SeismoGPT achieved high accuracy, with median normalized cross-correlation above 0.93, demonstrating its ability to maintain phase coherence and spectral energy distribution. The findings suggest that foundation models can be applied to physics-driven time-series forecasting, with potential uses in seismic warning and hazard mitigation, particularly for advanced gravitational-wave observatories.
